Abstract
The present invention relates to a liquid crystal composition for a light-scattering liquid crystal device shown in FIG.containing a polymerizable compound selected from the group consisting of compounds represented by the following general formula (1) as a first component and containing a compound having a negative dielectric anisotropy as a second component, a light-scattering liquid crystal device using the liquid crystal composition, and a smart window using the light-scattering liquid crystal device. A reverse mode type light-scattering liquid crystal device can have excellent transparency when no voltage is applied and a reduced driving voltage by the liquid crystal composition of the present invention.
